Adobe Acrobat could not open

[German HD]

Hello everyone
I have an updated Acrobat Pro DC license.

I try to open any pdf file from my computer and it gives me the following error

"Adobe Acrobat could not open '.....pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).. ...

However, the files are pdf and are not damaged.

Could someone tell me how to do it?
Thank you

Hi there

Hope you are doing well and sorry for the trouble.

Have you created these PDF files or have you got them from a different user? Please try to create a new PDF file and then try to open it and check.

Also make sure you have the recent version 22.1.20117 (Win), 20112 (Mac) installed. Go to Help > Check for updates and reboot the computer once.

Also, if the files are stored on a shared network/drive, please download them to your computer locally and then try to open them and check.

Also, please go through the correct answer marked in the similar discussion https://community.adobe.com/t5/adobe-acrobat-online-discussions/cannot-open-pdf-file-says-not-suppor... and see if that helps.

Also, go through the help page https://helpx.adobe.com/acrobat/kb/pdf-error-1015-11001-update.html and check if that works. 

Regards

Amal
